Joint rotor head of a rotary aeroplane with a leaf root coupling.

摘要

Rotorcraft rotor head of the type comprising a hub connected to each blade (2) of the rotor by means of a linking member which is integral with the said blade (2) and which is linked to the hub body via a laminated spherical stop. Each blade (2) is equipped with an assembly (20) for elastic drag recall with incorporated damping, one of whose ends (22) is linked to the member for linking the blade to the hub body. The linking member is constituted by an intermediate cuff (11) comprising a ring-shaped part (12) and a part equipped with at least one double clevis (14), the intermediate cuff (11) being a single-piece monobloc assembly whose ring (12) surrounds the laminated spherical stop with which it is integrated and whose double clevis or clevises (14) interact with means of integrating the blade (2). …??Application to the rotors of helicopters. …IMAGE…
